Project description:We have performed analyses of murine primary bone marrow derived monocytes challenged with either PBS or oxLDL. oxLDL selectively enhances growth and adhesion potential of monocytes. Purified bone marrow monocytes were treated with PBS or 20 microgram/ml oxLDL for a five day period, and cells were harvested for scRNAseq analyses.
Project description:Innate immune memory is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components. In this study we apply epigenetic, H3K27ac and H3K4me3 ChIP-seq, analysis to healthy human monocytes exposed to oxidized Low Density Lipoprotein (oxLDL), in vitro.

In this study we apply RNA-seq analysis to healthy human monocytes exposed to oxidized Low Density Lipoprotein (oxLDL), in vitro.
Project description:total RNA profiling of human primary monocytes comparing control untreated oxLDL cells with oxLDL cells for different time (6h and 12h), The latter makes monocytes to macrophage and foam cells.
Project description:The data submitted is for the proteomics data published in the paper: Quantitative proteomics reveals a role for epigenetic reprogramming during human monocyte differentiation D Nicholas, H Tang, Q Zhang, J Rudra, F Xu, W Langridge, K Zhang Molecular & Cellular Proteomics 14 (1), 15-29.
Project description:Innate immune memory is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to microbial components such as Beta glucan or the BCG vaccine. Here we characterize the transcriptional events following oxidized low-density lipoprotein (oxLDL) duced trained innate immunity using RNA-seq data.
Project description:DNA microarrays were used to investigate global gene expression patterns in cultured human umbilical artery endothelial cells (HUAECs) exposed to 1 nmol/L estradiol and/or 100 µg/ml oxidized low density lipoprotein (oxLDL) for 24 hours compared to control cells. HUAECs from 15 separate cultures were exposed to control (0.1% ethanol), 1nmol/L estradiol, 100 µg/ml oxLDL, or 1nmol/L estradiol + 100 µg/ml oxLDL treatments for 24 h. Total cellular RNA was extracted. Equal amounts of RNA extracted from 3 control cells or 3 estradiol-treated cells obtained from three different cultures were pooled, achieving five biological replicates of the control, five replicates that were treated with estradiol, five replicates that were treated with oxLDL and five replicates that were treated with estradiol+oxLDL . Therefore, a total number of 20 microarrays were developed.
Project description:Elutriated monocytes from 9 healthy donors with ApoE3/E3 genotype were differentiated for up to six days in vitro to macrophages using rhMCSF under serum-free conditions. Samples were taken on days 1, 4, 5 and 6 and analyzed for their transcriptomic profiles. After four days of differentiation cells were loaded for 24 hours with enzymatically modified LDL (eLDL, 40 µg/ml) or mildly oxidized LDL (oxLDL, 80 µg/ml). Finally on day five, lipid deloading was performed in serum free medium containing M-CSF and cells were incubated another 24 h with HDL3 (100 µg/mL).
